Power Feedback Output.
Be sure to connect a 22uF tantalum capacitor for frequency compensation and
a 0.1uF capacitor for noise de-coupling. Then connect this pin through a
ferrite bead to PWFBIN (pin8). The connection method is outlined in section
7.11 3.3V Power Supply and Voltage Conversion Circuit, page 22.
